Valve ain't feel that is worth the work for doing, they prefer to focus in PC and then make a good port to the PS3 than spending time and money in the PS3. You can't compare them with SE, Capcom, Ubisoft etc etc, why? Because They are mainly Console publisher, so they have to do it for most if not all the consoles, Valve on the other hand is mainly a PC, the X360 is just a plus, they wouldn't do if it wasn't so easy to port from PC to it.
